Pamela Anderson doubles down on claims Tim Allen flashed her after his blunt response

Pamela Anderson has doubled down on her accusations that Tim Allen sexually harassed her while preparing to film an episode of his '90s sitcom Home Improvement.

"No, it never happened. I would never do such a thing, Allen's statement said.

"This true story is just one of many surreal and uncomfortable situations I learned to navigate," she said.

"My book goes into how it made me feel over the course of my life and, in this case, my career. I have no ill will toward Tim. But like the rest, it should never have happened."

She wrote in Love, Pamela: "On the first day of filming [Home Improvement], I walked out of my dressing room, and Tim was in the hallway in his robe.

"He opened his robe and flashed me quickly — completely naked underneath.

"He said it was only fair, because he had seen me naked. Now we’re even."

As it was Anderson's first day on set, it is presumed that Allen was referring to the then 23-year-old posing for Playboy.

Anderson was Playboy magazine's Playmate of the Month in February 1990.

Home Improvement was one of Anderson’s first acting credits, appearing as Lisa in 23 episodes of the classic sitcom across seasons one and two.

She left right before she made it big on Baywatch, and the rest, as they say, is history.

In the lead-up to Love, Pamela dropping on January 31, the now-55-year-old has also spoken out against the Pam & Tommy series that was done about her infamous sex tape leak.

The Hulu show focused on her high-profile relationship with Tommy Lee and their subsequent marriage in the 1990s.

During this time, a sex-tape of theirs was stolen and shared without their consent.

Elsewhere in the tell-all, Anderson claims she was 'saved' by her children in the wake of her catastrophic collapse of a marriage with the Mötley Crüe drummer.

Her sons Brandon, 26, and Dylan, 25, were just toddlers when she filed for divorce from their father in 1998, and she admitted being a parent gave her something to focus on in the time that followed.

She said: "They saved me. I don’t want to put that on my kids but having children changed everything."

“Brandon is really creative and is this fiery kind of kid. Dylan is more introspective and more Zen. It’s a good team," she said.

She added: "She wrote: “Brandon and Dylan are true miracles, considering their gene pool. They have been through so much, yet they are not full of holes."
